Patented Sept. Si), 193() EMIL T. BERGQUIST, 0F CHCAGO, LLENOIS TONGSApplication filed January 9, 1930.

rllhe invention relates to tongs for handling ice cubes and othermaterial and has for its ohject the provision ot tongs of the typeemploying pivoted jaws, and employing a spring retracted plunger forholding the jaws normally in closed position oi' spring actuated meansto hold the jaws in open position when the spring closing means arereleased.

rlhe invention will be described in detail hereinafter and will he foundillustrated in the accompanying drawings in which Figure l a view inelevation oit the improved tongs,

Figure 2 is a similar view partly broken away, and in section, and

Figure 3 is a transverse eetional view on a plane indicated by the lineof i lgure 2.

ln the drawings similar reference characters are used to designatecorrespondii'ig parts in all ot the views.

rI'he improved tongs have a tubular stem l on which is slidably mounteda plunger 2 having an operating head 3 on one or" its ends and a nut elthreaded on the other end. The stem l is provided with hitureated ears 51oetween which are pivoted curved jaws 6 as shown at 7, each ot saidjaws being provided with a lug S that is engaged by the nut i to holdthe jaws in closed position. The stem l is provided with a partition l)intermediate of its ends and slidaloly mount ing the plunger 2 andformino' a hearing :for springs l0 and 'll on opposite sides of saidpartition 9, the spring l0 also normally engaging the head fl andtensioned to hold the head 3 outwardly ot the stein l to hold the jawsin closed position. The spring ll engages a dish l2 slidaoly mounted onthe plunger 2 and engaging' the lugs 8 on the sides opposite to thesides engaged hy the nut d and said sprina 'il operates to expand thejaws 6 to the position shown in broken lines in Figure Q by pressureagainst the disk l2 when the spring l0 is compressed by inward movementIof the head 3. vThe spring 10 is of greater tension than the spring iland operates to Close the jaws against the action of the spring l1 whenSerial No. 419,696.

pressure on the head 3 is released. i3 indicates a circumferentialflange that forms a linger hold Jtor the tongs when in opera-- tion.

lVhat is claimed is:-

Tongs, comprising a tubular stem, a plunger slidahly mounted in saidstem, a partition in said stem mounting the plunger, jaws pivotallysecured to said stem, lugs on said jaws, a nut adjustably mounted on theplunger and engaging said lugs, a disk slidable on the plunger andengaging the lugs, an enpansible coil spring enclosing the plunger,terminally engaging the partition and dislr and providing means to openthe jaws, an operating head on the plunger, and a spring enclosing theplunger and terminally engaging the partition and head7 the secondmentioned spring being of greater tension than the tirst mentionedspring and providing means to close the jaws and hold them in closedposition.

In testimony whereof I atlix my signature.
